Application mid J'nne18,1906- Bertallo. 322.144; t

To all whom it may comer-m Be it known that 1, ORANGE O. OZIAS, a citizen of the United States, residing at Dayton, in the county of I Montgomery and State of Ohio, have invented certain cate the money value of merchandise placed upon the i goods-receiver, or pan, at different prices-per unit.

A further object of the invention is to provide a scale.

of the type mentioned with an osgillatory indicator adapted to indicate fractional values and fractional weights.

The invention contemplates the employmentof an- -even'balance scale mechanism, preferably of the ual' arm type with the goods-receiver, or pan, on one side, and the receiver for the counter-weights on the oppo site side of the fulcrum, and a price or value indicating mechanism controlled and operated-by the -checkdevices, employed for maintaining'thepan in: upright" position, said price and value indicatingmechanism embodying a revoluble drum having-weight and price indicating characters on the periphery thereof, drum being adapted to revolve a stationary casing having a sight-slot therein, through which are exposed the weight and value characters corresponding to the merchandise upon the goods-receiver.

The invention consists generally in an e'ven balance scale combined witha spring counter-balancing.mech-- anism operating to control anjindicator for indicating weights and values when the scale is over-loaded: or

loaded beyond his balancing point.

in view,.as will appearfrom the specification, the in-, vention consists in certain novel details of construction and combinations and arrangements of parts as hereinafter described and set forth in the claims.

Referring to the accompanying drawings Fig'ure ing my'invention. Fig. 2 is a verticalsectionalview F of the assembled machine. Fig. 3 is a detail vie wioi the indicating drum.-- Figs; and 5 are detail viewsoi I tionary casing, a about'the revoluble' indicator."

The checklinks, 1: J, extend in opposite di rections frpmthe c d, cach 'pivotally connected at one end to the upper end' of itsarm and piv- 'otally connected at the opposite end to the interior of the housing. The'pivotal' connections are, similar in all respects to the pivotal connections used with checklinks in scales as heretofore constructed no detail. description is necessary herein.- J r Thescal'e asthus far describedconstitutes aneven balance scale oi the equal armtypegthec'oimter-po ise weights on one arm being adapted to balance is load equalweight on the other arm ofthe' scale. In on. i

to make the 'scale a price scale, a 'weightand value indicating mechanism is introduced as follows: Supported-upon the arms, a, isa cylindrical casing, a;

whih lcontains weight and price-indicating mechangenerally to the type of scale known asthespring balance scale. -It embodies an oscillatory-cylinder drum, c', havingupon its peripheral- 4 surface computations of value and weight which are exat a sight openings, in'the irontof'thacasing, a. The'c ylinder, e, is mounted to rotat on a central'spindle having pinions, "0 at the ends thereof, with which rack bars, e, m'esh,- said.rack bars being in turn connectedto' s horizontal rod, 6*, which constitutes a part ofthe runner or loadshp porting device. To counter balance theload and. the supporting devices as well 'as'to return the drum t6 its initial position,-counterbalancing springs, f, are preferably located at each.

end of the drum, and connected atthetop the casing, a. The springs, f, at their'lower end are connected by a horizontalibar, f, centrally connected with'the bar, c adjoining the rack bars, by means of the load-supporting hook, f.' A suitableiconnection,

' g, is provided on the stem, 0, and a link, 9, extends ,from said connectiom g', to the load supporti ng hook, f.' .The connections between the igoods-receiving pan, 0, and the revoluble drum, 'e, are such that any vertical movement of the goods-receiving pan is transwill equal the indicated weight plus the weight of the counterpoise on the weight receiver of the even balance device. I It will be readily, seen that by the construction described, the even balance devices may be utilized for the purpose of tare; thi s weights may be placed upon the receiver, 11, to counter-balance the weight of a receptacle previously placed upon jthe goods-receiver, 4 0, and the weight and value of *a commodity subsequently placed within the receptacle will be readily and quickly indicated through the movement of the oscillatory drum, e, and may be read in characters of weight'and value through the sight opening, c. The device may also be utilized for ascertaining weights beyond the capacity of the indicator. For instance" if the indicator drum is graduatedhto indicate the weight and value to the extent of ten pounds, and it is v desired to weigh merchandise of approximately seventeen pounds, the merchandise being placed upon the goods-receiver and a ten pound counterpoise placed upon the weight receiver, the indicator will then indicate the weight and value of the difl'erence between the counter-poise and the merchandise which in this case would be substantially seven pounds. The value of the commodity in tens of units-is readily computed by mental process, to which is added the value of the remainder as indicated upon the oscillatory indicator,

which will give the value of the bulk of merchandise upon the goods-receiver.

From the above description, it is apparent that'there has been produced a weighing scale possessing the features of advantagehereinbeiore. enumerated as desirable, and which obviously is susceptible of modification in its form, proportion, detail construction and arrangement of parts, without-departing from the principle involved or sacrificing any of its advantages.

Having thus described my invention,- I claim:

1. In a price scale, the combination with a lever, 21 goods-receiver and a counterweight receiver carried by said lever, upwardly extending check arms connected with said receivers, links for maintaining the'horlzontai parallelism of the receivers, an indicator located above the receiver, and links connected with said indicator extending substantially in right angular position to said flrstmcntioned links, and a connecting arm between said lastmenbalancing lever, a goods-receiver and a counterweight receiver pivotally carried by said lever, an indicator, movable link members connected atone end to said receivers and at the other end to a stationary part of the scale frame or support, connecting members placed in right angular relation to the said links, said connecting member,s' being connected to the indicator and also to one of the; receivers, substantially as specified.

. In a price scale, the combination with a lever piv- ,oted intermediate its ends, a goods receiver and a counterweight receiver-carried on opposite ends of said lever, pivotally extending arms connected to each of said levers, and links connected to each of said arms and to a stationiiry part of the frame or support for maintaining the parllelism ,of said receivers, a cylindrical rotating indicator, and a connecting member extending parallel with the axis of isaid rotating indicator and connected at each end \to said indicator, said connecting-member being arranged at right angles to said links and connected to one of said receivers, substantially as specified.

4. In a price scale, the combination with an indicator and a casing surrounding the indicator, of a counterbalancing lever, a goods-receiver and a counterweight re ceiver carried by said lever, upwardly extending check arms, and links connected with said arms for maintaining the parallelism of the receivers, crossbars above said first-mentioned links,'.and an arm connecting said crossbars with one of saidcheck arms, connections at the ends' of the cross-bars extending to the indicator, and connections also located at the end of the cross-bars connected with the stationary casing of the indicator.

5. ln a price scale, a counterbalancing lever, B. goods receiver and a weight-receiver pivotally carried at the respective endsof said lever, a set of links connected with said receivers for maintaining the parallelism thereof, a rotary indicator, a bar having a driving connectioh at each end to said'indicator to impart rotary movement thereto and also having a connection at each end with a counterbalancing spring, and a connection between said bar ajnd one of said receivers substantially as specified.

In itestimony whereof, I have hereunto set my hand this 14 day of June D. 1906. I
